Corrosion of third degree of right hand, unsp site, subs

This code signifies a severe chemical burn affecting the right hand, characterized by full-thickness tissue destruction extending through all layers of the skin and potentially into underlying structures. The specific location on the right hand is not documented. This code is used for encounters following the initial treatment of the injury.

Apply this code when a patient presents for follow-up care, wound care, or management of complications related to a previously treated third-degree chemical burn of the right hand. This includes situations where the patient is receiving ongoing treatment, rehabilitation, or monitoring for healing progress.

• Ensure documentation clearly indicates a "subsequent encounter" for this specific injury, not the initial treatment.
• Verify the burn is explicitly stated as a "corrosion" (chemical burn) and not a thermal burn.
• If a more specific site on the right hand is documented (e.g., finger, palm), a more precise code should be selected.
